. volving a. high speed stock quotation ticker of the type recently adopted and projecting machine for projecting images of the markings formed by the ticker onto a screen.

With the stock quotation projecting machines at present in use, when a ticker comes to rest after transmitting a message, a number of quotations are located on the portion of the tape disposed between the ticker and the projection aperture, images of which quotations consequently will not be projected until the ticker resumes its operation, and as a result of this condition, if the period of rest endures for any considerable length of time, the trader who is being guided by the screen will naturally be at a disadvantage as compared to the trader who is following the tape direct.

In view of the foregoing, the present invention aims specifically to provide an improved stock quotation projecting machine in which after a message is transmitted by the ticker, and the printing operation comes to rest, the feed of the tape will continue until the last quotation printed is projected before the feed also comes to rest.

These and other features, capabilities and advantages of this invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawing in which Figure 1 is a front elevation of a stock quotation projecting machine showing the wiring diagrammatically and part of the control mechanism enlarged in association with the wiring;

Fig. 2 is a fragmental section on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged fragmental detail of another portion of the control mechanism; and

Fig. 4 is an enlarged fragmental detail of still another portion of the control mechanism.

In the embodiment illustrated, there is shown a standard lamp housing I, having a lateral extension 2 provided at the upper end thereof with a light aperture extending the full length of the extension across which the tape '1' passes, as a result of which the light rays from the lamp 3 being deflected by the deflector 4 pass upwardly through the tape T and then through the objective lens contained in the housing 5 to form images on the deflector 6, which are deflected onto the REISSUED deflector 1 and then deflected onto the screen 8 in the usual way.

The housing 5 of the objective lens is secured at the upper end of a bracket 9 extending upwardly from the lamp housing I. The tape T in 5 the usual way extends from the supply reel l0 formed on the ticker ll diagrammatically shown, down below the abutment l2 and then up under the feed roller l3 of the ticker in engagement with which the tape is normally pressed by the 10 pressure roller l4. From the feed roller l3, the tape T passes over the guide l5 and then down under the flnger l6, and up over the guide I I and then under the finger ll! of the lever l9 pivotally connected at 2| to the bracket 20, and then over the light aperture formed at the top of the extension 2 down to and under the idler 22 formed on the housing 23, and then over the tape, pulling roller 24 in engagement with which the tape is maintained by the pressure roller 25, then under the idler 26 and then to the rewind reel 21 pivotally mounted on the shaft 28 fulcrumed in the upper end of the bracket 29. The shaft 28 of the rewind reel 21 has mounted thereon the pulley 30 which is connected by the spring belt 3| with the pulley 32 connected to the reduction gearing mounted in the housing 23. The tape pulling roller 24 is also connected to the reduction gearing (not shown) mounted in the housing 23. The reduction gearing has a shaft 32, which has formed thereon a pulley 33 connected by the belt 34 to the pulley 35 mounted on the shaft 36 of the motor 31.

The finger l8 in the present instance serves as the vibration dissipating device, the pressure of .35 which on the tape is adjustable by the weight 38 adjustably mounted on the arm IS. The extension 39 of the arm I9 is provided with an adjustable stop 40 to determine the distance of movement of the arm I 9 and also to cooperate with the 40 finger l8 to maintain the portion of the tape T located at the light aperture, smooth and even throughout when the tape T is at rest.

The control mechanism now to be described forms the main subject matter of the present invention.

The pressure roller l4 of the standard ticker is mounted on a bracket 4|, which has a laterally extending finger 42, which has heretofore been used as an engagement point for the finger of the attendant to depress the pressure roller l4 in order to facilitate threading the tape T between the feed roller l3 and pressure roller I4.

Use is made of this finger '42 so that the pressure pressure roller l4 against the tension of the spring 48 to liberate the tape T from frictional engagement with the feed roller I3. The magnet 43 is connectedby the conductor 49 with one of the terminals of the fluid mercury switch 58, the other terminal of which is connected to the circuit breaker 5|, by the conductor 52. The magnet 43 is also connected to the fluid mercury switch 53 mounted on the bracket 54 pivotally connected to the stub shaft 55, the conductor 56 extending from the magnet 43 to the terminal 51 of the mercury switch 53. The mercury switch 53 is provided with two additional terminals 58 and 59, the terminal 58 being connected to the circuit'breaker 5| by the conductor 58. From the foregoing, it-will appear that when the mercury switch 53 is disposed in the position indicated in Figs. 1 and 3 and the circuit breaker 5| is connected to the main source of supply indicated by the leads SI and 62, and the switch 58 is disposed in the position indicated in Fig. 1, the magnet 43 will be de-energized since the mercury defined by the dotted line 83 clears the terminals.of the switch 58 to break the circuit at that point, although the mercury defined by the dotted line 84 of the switch 53 is in position to establish a circuit from the terminal 51 to the terminal 58. In such position, the pressure roller M will be free to press the tape T against the feed roller l3, ready to feed the tape upon the initia'll message transmitting impulse of the ticker In order to rock the switch 58 to cause the mercury thereof to bridge the terminals 85 and 68, the mechanism now to be described is provided. The bracket 54 is provided with an arcuate slot 81 to receive the fixed pin 88, which determines the distance of throw or movement of the bracket 54 about the pivot pin 55. The

bracket isalso provided with an extension 69,

which is connected by the spring 18 to the arm 1| pivotally connected at 12 to the bracket 54, which arm in turn is provided at its free end with the finger l6 resting on the tape T between the abutments l5 and I1. The terminal 59 of the switch 53 is'connected by the conductor 13 with the magnet 14, which is connected by the conductor 15 to the conductor 52, extending to the circuit breaker 5|. The magnet 14 is preferably mounted on the bracket 18, having an extension 11 on which is pivotally mounted the armature .18, the extension 19 of which is connected by the spring 88 to the abutment 8| to urge the armature 18 upwardly away from the magnet 14.' The bracket 18 has 0 an extension 82 at the upper end of which is pivotally mounted the housing 83 in which the mercury switch 58 is'secured. One end of the housing 83 is connected by the spring 84 with the free end of the armature 18.

The housing 83, spring 84 and armature 18 thus the pin scend and carry with it the bracket 54, in turn to rock the cartridge 53, so that the mercury therein will clear terminal 51 and bridge the terminals 58 and 59 as a result of which the magnet 3'8 will be energized to attract the armature 18,

depressing it into the dotted line position of Fig. l in turn to rock the'cartridge 58 into the dotted line position of Fig. 1, to cause the mercury in thecartridge 58 to bridge the terminals 95 and 55. The current for the motor 31 will be established when the mercury in the cartridge 58 is thus caused to bridge the terminals 65 and 86, the terminal 66 being connected by the conductor 85 to one of the terminalsof the motor 31, and the other terminal of the motor 31 being connected by the conductor 86 to the rheostat 81, which is connected by the conductor 88 to the conductor 88.

The armature 18 as shown in Fig. 1, is connected by the link 89 with a dash pot, permitting the quick and immediate closing of the circuit after the ticker starts operating from a period of rest. This dash pot, however, controls the armature 18 to retard its ascent after the ticker has come to rest from a message transmitting period to maintain the cartridge 58 in circuit making.

absorbs the loop and causes the finger I6 to ascend, contact is broken between the terminals 58 and 59 and contact is established between the terminals 51 and 59 energizing the magnet 43 to withdraw the pressure roller M from the tape. The tape roller 24 will then continue drawing the tape T across the light aperture as aforesaid until the last quotation printed will have reached the light aperture to be projected or as otherwise predetermined.

Any suitable dash pot, preferably adjustable, may be used and so control the armature 18. In the present instance, there is provided a cup 98, containing an oil bath 9| and a sleeve 92 to which the link 89 is pivotally connected. The sleeve 92 is provided with a disc 93, having an opening 94 and an adjustable pin 95 screw threadedly connected to the disc 93. Below the disc 93, the sleeve 92 is provided with a second disc 91, having a valve opening 98 provided with a ball valve 98 and a second valve opening 99 into which the tapered lower end of the pin 95 extends, the clearance between the pin 95 and opening 99 depending upon the retarding effect to'be produced. From the foregoing, it will be clear that when the magnet 14 is energized to attract the armature 18, the valve ball 98 will clear the opening 98 to permit the oil 9| freely to pass therethrough and up through the opening 94 and, of course, some oil will also pass up through the opening 99 and the clearance formed by the pin 95, and, on the other hand when the sleeve 92 is in its lowermost position, and the magnet 14 is then de-energized,

.to permit the spring 88 to raise the armature 18,

that the 011 above the disc 99. can only pass below the disc 91 through the clearance formed between 95 and orifice 99.

From the foregoing, it will thus appear that in the slow upward movement of the sleeve 92, the cartridge 58 will be maintained in circuit making pulling device for drawing the tape away from i position where the current to the motor 31 and to the magnet 43 will be maintained until the free end of the armature 18 has passed above the pivot point of the housing 83 and the spring 84 also extends above the pivot point of the housing 83 to permit the tension-of the spring 84 to snap the housing 83 into-the position in full lines illustrated in Fig. 1, where it will cause the mercury contained in the cartridge 50 to clear the terminals 65 and 66.

As a safety feature to protect the tape from any undue drawing effect, resulting from the momentum of the motor after the current has so been interrupted by the movement of the cartridge 50,

in which position the pressure roller M will be free again to press the tape against the feed roller l3,'the spring 10 is provided to permit the arm 1| to be raised an additional distance. The tension of the spring 10 and this movement of the arm II will, of course, be determined according to the momentum of the motor and tape pulling mechanism to be used.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
